Application of 1640-39-7, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 1640-39-7, name is 2,3,3-Trimethylindolenine. In an article，Which mentioned a new discovery about 1640-39-7
An unusual aromatic substitution to access indolenines is described. 2-(2-Methoxyphenyl)acetonitrile derivatives are reacted with various alkyl and aryl Li reagents to furnish the corresponding indolenine products, constituents of natural products, and cyanine dyes such as indocyanine green. This new method was used to synthesize 41 indolenines with large functional group tolerance, and selected examples were further converted to the corresponding indolenine dyes. Key experiments provide insight into the mechanism of this nucleophilic aromatic substitution.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.1640-39-7. In my other articles, you can also check out more blogs about 1640-39-7
